Film peeling and winding method and device thereof

The present invention relates to a method and apparatus for peeling and unwinding a film for peeling off a film attached to a surface of various sheets.

The liquid crystal display panel is attached with a polarizing plate film on the surface of the glass substrate to be used, but in the attaching step of the polarizing plate film, foreign matter or bubbles may be mixed between the glass substrate and the polarizing plate film. Happening. In this case, it is necessary to peel off the polarizing plate film from the glass substrate to reuse the glass substrate. Of course, it is not limited to peeling off the polarizing plate film from the glass substrate, and includes, for example, peeling off the protective film attached to the printing plate material after exposure, or after exposing the photosensitive film attached to the printed substrate. Since the peeling is removed, etc., there are many opportunities for peeling off various films attached to the surface of the board. Under the circumstances, various related techniques have been proposed in which the entire film is not peeled off by manual work, but at least one corner portion of the film is peeled off from the surface of the sheet, and the film is peeled off mechanically.

In the case where the film attached to the surface of the sheet is peeled off by manual work, the end portion of the film is peeled off from the surface of the sheet by a suitable method, and then pulled in a direction overlapping with the film attached to the surface of the sheet, The ability to fold the film attached to the surface of the sheet from the surface of the sheet while smoothly peeling off is known to anyone, and the closest thing to the method of peeling and winding is in The peeling and winding device for a cover film described in Patent Document 1 proposes a method for mechanically peeling off a film attached to a surface of a sheet material.

[Patent Document 1] Japanese Patent Laid-Open No. Hei 5-80529

The method described in the above Patent Document 1 is a method of moving a sheet material and a corner portion of a film peeled off from the surface of the sheet material, and moving the peeled film in a direction overlapping the film attached to the surface of the sheet material, and using The peeling of the film was carried out under the same conditions when the manual work was torn off. However, on the structural surface, the adhesive roller configured to tear a corner portion of the film rotates the film corner attached to the surface of the adhesive roller to the upper side of the adhesive roller, and the adhesive is adhered thereto. After the drum is wound and the film of the desired length is torn off, the adhesive roller is raised, and the other peeling guide rollers are introduced into the lower side of the adhesive roller. The peeling guide roller and the plate are horizontally moved relative to each other while the film is stretched. Pull up from the peeling guide roller. Therefore, even if the film is directly wound by rotating the rising adhesive roller, in addition to the adhesive roller, a peeling guide roller that relatively moves horizontally with respect to the plate material is required, so that the structure is extremely complicated and the control becomes relatively simple. difficult.

The present invention proposes a film peeling and winding method capable of solving the above-mentioned conventional problems, and in order to easily understand the relationship with the later-described embodiment, the film peeling and winding method of the present invention is used in the description of the embodiment. When the symbol is attached to the parenthesis, the film peeling and winding method uses a film peeling and winding device which is horizontally supported at a certain height above the plate support water level and can be at the axis a film winding drum (29) that rotates around and traverses in a horizontal direction perpendicular to the axis, and a film holding member (37) is disposed at an intermediate position in the longitudinal direction of the film winding drum (29). The sheet material (P) having the peeling target film (F) attached to the surface thereof is placed obliquely on the sheet supporting water level with respect to the traverse direction of the film winding drum (29), and is applied from the sheet (P) surface. After a corner (Fc) of the peeled film (F) is held by the film holding member (37) of the film winding drum (29), the film winding drum (29) is wound around the film. The film (F) of the winding drum (29) is rotated and traversed in the direction between the film winding drum (29) and the film (F) on the surface of the sheet (P) on the lower side thereof, and is transverse The film winding roller (29) is moved rearward to ensure that the film (F) peeled off from the surface of the plate (P) is in a state of being pulled toward the front (Fa) of the film winding drum (29). Peeling and winding of the film (F).

Further, the present invention also proposes an apparatus suitable for the method for performing the above-described film peeling and winding. That is, the film peeling and winding device proposed by the present invention has a film which is horizontally supported at a certain height above the plane of the sheet supporting water and which is rotatable around the axis and traversed in a horizontal direction perpendicular to the axis. a winding drum (29) is disposed at an intermediate position in the longitudinal direction of the film winding drum (29), and in the film peeling and winding device, the film holding member (37) is On the inner side of the opening portion (53) provided in the cylindrical drum main body (30), it is disposed adjacent to the circular drum main body (30) in the circumferential direction of the circular drum main body (30) to close the opening portion (53). The fixed receiving seat (38) and the opening and closing holding piece (39) are covered at the front end portion (39a) from the outer side of the cylindrical drum body (30) to cover the fixed receiving seat. In the state of (38), it is pivotally supported around the axis parallel to the axial center of the cylindrical drum main body (30), and is driven to open and close by the clamping drive element (48). Inserting a film corner (Fc) inserted between the front end portion (39a) and the fixed receiving seat (38) via the opening and closing clip Sheet (39) sandwiched between the closing movement of the front end portion (39a) fixed to the receptacle (38).

According to the above method for peeling and winding a film of the present invention, the film peeled off from the surface of the sheet by the traverse of the film winding drum can be surely directed toward the film winding drum behind the traversing film winding drum. The area pulled forward, and since the film in the area is not directed to the upper side of the film winding drum, but is directed to the lower side of the film winding drum, the film in the area is overlapped on the surface of the sheet and The way the film is about to be torn is bent and torn off. Therefore, since there is almost no possibility of applying an upward force to the sheet due to tearing of the film, there is no adverse effect on the sheet used again, and the required force for traversing the film winding drum is only required. With less, the film can be peeled off smoothly. Further, since the torn film is simultaneously wound by the traversing film winding drum, the film winding roller as the traverse member can be greatly reduced as compared with the case where the film is simply detached by the traverse member The traverse distance. Further, compared with the case where the guide roller that turns the torn film to the upper side in order to reduce the traverse distance of the traverse member and the device that traverses the element that pulls the film upward is integrally traversed, the device can be greatly Miniaturization and the goal of significantly reducing costs.

When the film peeling and winding method of the present invention described above is carried out, the corner portion (Fc) of the film (F) peeled upward from the surface of the sheet (P) is maintained in the original direction by being located in the film winding drum (29) The film holding member (37) on the lower side of the shaft is sandwiched, and the film (F) peeled off from the surface of the sheet (P) by the rotation and traverse of the film winding drum (29) Turning to the opposite direction of the traverse direction of the film winding drum, and winding the film (F) wound on the film winding drum (29) in this state, the film held by the film holding member (37) The corner portion (Fc) of (F) is bent in the opposite direction to perform tearing and winding of the film (F).

According to this method, since the film corner portion can be sandwiched by the corner portion of the film abutting on the receiving surface along the circumferential surface of the film winding drum, the film holding member has a simple structure and can be easily and surely The corners of the film are held in the vicinity of the circumferential surface of the film winding drum. In addition, when the film is torn and wound from the surface of the sheet by the rotation and traverse of the film winding drum, the film winding roller is utilized. The film corner portion held by the film holding member of the cylinder is bent in a direction opposite to the film wound around the film winding roller, so that when the film winding roller starts to pull the film winding action, There is a possibility that the corners of the film are pulled out from the film holding member due to the tension applied to the film. Therefore, it is not necessary to excessively increase the holding force of the film holding member, which also makes the structure of the film holding member simple, can be carried out at an inexpensive price, and can reliably perform tearing and winding of the film.

Further, by the rotation and traverse of the film winding drum (29), when the film (F) peeled off from the surface of the sheet (P) is formed toward the region (Fa) which is pulled forward by the film winding drum (29) Preferably, the film (F) is torn and wound in a state where the peripheral speed of the film winding drum (29) and the traverse speed of the film winding drum (29) are substantially equal to each other. . According to this method, the length of the region in which the film is pulled forward is maintained to be close to a certain length from the surface of the sheet until the film winding drum is reached, until the winding end position of the film is torn around the film under the same conditions. Winding, and from the winding end position of the film, the film winding drum is only traversed by an extra portion of the length of the region, so that the tearing and winding of the film on the surface of the sheet can be surely achieved, and the device can be easily performed. control.

Further, the above-described film peeling and winding device of the present invention can be used in a device capable of rotating and traversing a film winding drum in accordance with the above-described method of peeling and winding a film of the present invention, particularly in a film winding drum. A part of the circumferential surface can be formed between the fixed receiving seat and the front end portion of the opening and closing holding piece and formed in a film corner insertion slit parallel to the axial direction of the roller. Further, the slit is formed in a cylindrical shape. The outer side of the drum body covers the inner side of the front end portion of the opening and closing holding piece of the fixed receiving seat, and is not a slit that enters from the circumferential surface of the film winding drum toward the right angle of the drum axis, but can be formed to be wound from the film. The circumferential surface of the drum enters the gap inside the drum in a circular arc shape, so The corner portion of the film that rises from the surface of the sheet material obliquely rearward can be easily and surely inserted between the fixed receiving seat and the front end portion of the opening and closing holding piece. That is, the clamping of the corners of the film can be easily and surely performed.

Further, the above-described apparatus of the present invention can basically be configured such that the traverse of the traverse body and the rotation of the film winding drum are interlocked with each other by one driving element. For example, a traverse drive element (8) for traversing the traverse body (3) can be provided, and a pinion gear that is interlocked with the film winding drum (29) is pivotally supported on the traverse body (3) ( Pinion gear), and a rack gear that meshes with the pinion is laid along a traversing path of the traverse body (3). According to this configuration, when the traverse body (3) is traversed by the traverse drive element (8), the pinion gear traversed integrally with the traverse body (3) is engaged with the frame gear by the frame gear It is driven to rotate, so that the film winding drum (29) that interlocks with the pinion can be rotated.

However, when the above-described apparatus of the present invention is implemented, it is preferably configured to be supported in a traversing range of the film winding drum (29) so as to be horizontally movable back and forth and driven by the traverse driving member (8). a traverse body (3), and the film winding drum (29) is rotatably pivotally supported on the traverse body (3), and rotates the film winding drum (29) for rotation A drive element (motor (34)) is disposed on the traverse body (3). Since the traverse drive element and the rotation drive element of the film winding drum are independently configured, the traverse speed and the rotational speed of the film winding drum are independent of each other and can be freely controlled. Therefore, the film area on the rear side of the film winding drum can be ensured, that is, the method of the present invention can freely set the length of the area where the film is pulled forward from the surface of the sheet until it reaches the film winding drum. .

When the above structure is further employed, the clamping driving member (48) of the opening and closing holding piece (39) is housed in the cylindrical drum body (30) to be in the cylindrical drum body (30). In the axial direction, the movable movable body (40) on the inner side of the opening and closing holding piece (39) and the cam (cam hole (44) provided in the movable body (40) are supported in a movable manner. )) joint and from the opening and closing clamping piece (39) a cam follower piece (45), a push-pull drive exciter (46) provided outside the one end of the cylindrical drum main body (30), and provided on the traverse body (3), and a push-pull drive stimulator The device (46) and the sliding body (47) for the operating movable body (40) are supported by the cylindrical roller so as to be movable in the axial direction. The body (30) is coaxially disposed, and is provided with a push-pull transmission member (49) capable of relatively rotating around the axis of the cylindrical drum body (30) with the push-pull drive actuator (46). .

According to this configuration, the actuator that opens and closes the opening and closing holding piece is provided in the cylindrical drum body, and the cylindrical drum body and the actuator are integrally rotated, and pivotally supported. In the traverse body of the film winding drum, a rotation driving element for rotating the film winding drum and a push-pull driving device for holding the clamping driving element of the opening and closing holding piece can be distributed to both ends of the film winding drum. Since the actuator can easily configure the power supply system or the control system for the actuator that opens and closes the opening and closing clamping piece, and can be selected and set to be opened and closed without being restricted by the internal space of the cylindrical drum body. The gripper performs an opening and closing swing motion of the actuator. In addition, the element that opens and closes the opening and closing holding piece in the rotating cylindrical drum body is not used by a rotary type actuator that rotates in the same manner as the cylindrical drum body, but is used in a cylinder. Since the actuator for the push-pull operation is performed in the axial direction of the drum main body, the opening and closing clamp can be surely opened and closed without being affected by the rotation of the cylindrical drum main body.

The coupling member 51 at the inner end portion is coupled to one end portion of the operation movable body 40 by a coupling pin 52.

As described above, the circumferential surface of the fixed receptacle 38 is disposed in contact with the imaginary outer circumferential surface of the cylindrical drum body 30, and in order to open and close the protruding arc surface of the holding piece 39 and the imaginary of the cylindrical drum body 30 The outer circumferential surface is nearly uniform, and the cylindrical drum main body 30 of the film winding drum 29 is provided with a part for exposing the circumferential surface of the fixed receiving seat 38 and the opening and closing holding piece 39 as shown in Figs. 9 to 12 . The outer side of the opening 53 that protrudes from the circular arc surface. And the cylindrical drum body 30 is divided into two semi-cylindrical members 30a, 30b along the axial center at a position near the axial center of the fixed receiving seat 38, and in the final stage of assembly of the film winding drum 29, As shown in Fig. 7, the end portions of the two semi-cylindrical members 30a and 30b are fitted to the support small-diameter portions 31b and 32b formed at the both ends of the support shaft portions 31 and 32, and the two semi-cylindrical members are combined with each other. 30a, 30b to form a cylindrical drum body 30. In this state, the ends of the semi-cylindrical members 30a, 30b are fastened to the supporting small diameters of the support shaft portions 31, 32 by fastening tapes 54a, 54b. Parts 31b, 32b. Further, when the semi-cylindrical members 30a and 30b are attached, in order to accurately determine the position of the opening portion 53, as shown in FIG. 10B, one side of the opening portion 53 can abut against the circumferential surface of the fixed receiving seat 38.

According to the configuration of the film holding member and the holding drive member 48 configured as described above, the driving movable body 40 is pushed to the pushing limit position by the push-pull driving guide 46 and the push-pull shaft 47. In the ninth and eleventh drawings, the cam follower piece 45 on the side of the opening and closing holding piece 39 is pushed upward via the cam hole 44 of the operating movable body 40, so that the opening and closing holding piece 39 is around the front end of the support shaft 42 and at the front end portion. The 39a swings in a direction approaching the circumferential surface of the fixed receiving seat 38, and finally, the front end portion 39a of the opening and closing holding piece 39 is formed in a closed state in contact with the circumferential surface of the fixed receiving seat 38. In the state in which the operating movable body 40 is pulled to the pulling limit position by the push-pull driving guide 46 and the push-pull shaft 47, as shown in FIGS. 12 and 13, the holding piece 39 is opened and closed. The cam follower piece 45 is pushed downward through the cam hole 44 of the operating movable body 40, and the opening and closing holding piece 39 is swung around the support shaft 42 and the front end portion 39a is swung away from the fixed receiving seat 38, and finally the opening and closing holding piece is opened. The front end portion 39a of the 39 is formed in an open state in which the circumferential surface of the fixed receiving seat 38 is separated only by a certain interval.

In the following, the method of using the entire apparatus is described. As shown in Fig. 1, in the state where the traverse body 3 is at the traverse start position S, the rectangular sheet material P on which the surface film (polarizer film or the like) F is attached is obliquely placed. At a predetermined position of the horizontal base plate 1. At this time, the guide member G whose position is determined at one corner of the film peeling start target is a predetermined position provided on the horizontal base 1 without being affected by the size of the sheet P. After the sheet P is placed at a predetermined position on the horizontal substrate 1, the film portion of the film peeling start target of the film F attached to the sheet P is wound at a corner portion of the traverse body 3 at the traverse start position S. The central portion of the drum 29 in the longitudinal direction, that is, the position directly below the film holding member 37. On the other hand, the film winding drum 29 when the traverse body 3 is at the traverse start position S is as shown in Fig. 14, and the fixed receiving seat 38 is located directly below the axis of the film winding drum 29, and is relatively The opening and closing holding piece 39 of the fixed receiving seat 38 is located on the side opposite to the side having the traverse end position E, and the front end portion 39a is in an open state with respect to the fixed receiving seat 38.

After the preparation state is ready, the film corner peeling device 4 is operated, and as shown in Fig. 14, the corner portion Fc of the film F on the sheet material P is moved by the forward direction of the blade 4a of the film corner peeling device 4 The peeling blade 4b is peeled off from the surface of the sheet P. Therefore, one corner portion Fc of the film F is fixedly received at the position immediately before the front end portion 39a of the opening and closing holding piece 39 in the film holding member 37 of the film winding drum 29 as shown in Fig. 14A. The circumferential surface of the seat 38 abuts. In other words, in order to form this state, the positioning of the sheet material P on the horizontal substrate 1 and the traverse start position S and the thin film winding drum 29 are set. The starting posture of the film winding drum 29. Then, the push-pull drive actuator 46 is operated, and the opening and closing clamp piece 39 is closed and closed as described above. Therefore, as shown in Fig. 14B, the front end portion 39a of the opening and closing holding piece 39 sandwiches the corner portion Fc of the peeled film F between the circumferential surface of the fixed receiving seat 38. Thereafter, the blade 4a of the film corner peeling device 4 is returned to the standby position.

In order to surely sandwich the corner portion of the film F between the circumferential surface of the fixed receiving seat 38 and the front end portion 39a of the opening and closing holding piece 39, the circumferential surface of the fixed receiving seat 38 is preferably engraved with respect to the axis. Reticulated rills, etc., or roughing or attaching/coating other sheets or coatings with a large coefficient of friction to improve friction. Further, in the case where the circumferential surface of the fixed receiving seat 38 facing the front end portion 39a of the opening and closing holding piece 39 is worn, since both ends of the fixed receiving seat 38 are screwed at the axial center position, the screws 38a, 38b are loosened by the screws 38a, 38b. The fixed receiving seat 38 is rotated to move the position facing the front end portion 39a of the opening and closing holding piece 39 in the circumferential direction, so that the new circumferential surface can face the front end portion 39a of the opening and closing holding piece 39 to restore the clamping force. Needless to say, since the push-pull drive ejector 46 can continuously provide the closing power to the opening and closing holding piece 39 by the electromagnetic force, the corner portion Fc of the film F can be surely held at the front end of the opening and closing holding piece 39. Between the portion 39a and the fixed receptacle 38.

As described above, the corner portion Fc of the film F which is erected obliquely from the surface of the sheet material P is sandwiched between the front end portion 39a of the opening and closing holding piece 39 and the fixed receiving seat 38 while maintaining the posture. Then, the motor 24 of the traverse drive element 8 and the rotation drive motor 34 of the film winding drum 29 are operated to start the traverse body 3, that is, the film winding drum 29, from the traverse start position S to the traverse end position. E traverses and rotates its film winding drum 29. The rotation direction of the film winding drum 29 at this time is the direction in which the fixed receiving seat 38 at the position immediately below the axial center of the film winding drum 29 moves in the traverse direction of the traverse body 3 (film winding drum 29). . Then, the motor 24 of the traverse drive element 8 and the rotation drive motor 34 of the film winding drum 29 are controlled, and as shown in Fig. 15, the traverse body 3 (film winding drum 29) from the traverse start position S is set. The traverse distance L1 and the rotating film winding drum 29 wind the film F on its circumferential surface The winding length L2 is nearly equal, and thus the traverse speed of the traverse body 3 (film winding drum 29) is nearly equal to the rotational peripheral speed of the film winding drum 29.

As a result of the above control, as shown in Fig. 14A, the film F which is peeled off from the surface of the sheet P and stands up obliquely rearward is as shown in Fig. 15, and is pulled obliquely forward from the surface of the sheet P to become a film. A state in which the circumferential surface of the winding drum 29 (the protruding arc surface on the outer side of the opening and closing holding piece 39) is in the tangential direction is tangential. After this state, since the traverse distance L1 of the traverse body 3 (thin film winding drum 29) as described above and the winding length L2 of the wound film winding roller 29 wound on the circumferential surface thereof are nearly equal, Therefore, as shown in FIGS. 16A and 16B, even if the traverse distance L1 of the traverse body 3 (film winding drum 29) and the film winding length L2 of the film winding drum 29 increase, since L1 = L2 The relationship between the length and the angle of the film pulling region Fa from the front surface of the sheet P to the circumferential surface of the film winding drum 29 is almost constant. Fig. 17 shows a state in which the film winding drum 29 in the state shown in Fig. 16A is rotated by approximately 90 degrees in a plan view.

Further, after the winding of the film F is started, when the film pulling region Fa is formed as shown in Fig. 15, it is sandwiched between the fixed receiving seat 38 of the film holding member 37 and the front end portion 39a of the opening and closing holding piece 39. The corner portion Fc of the film F is curved in a direction opposite to the film pulling region Fa. Therefore, by the tension of the film pulling region Fa after the state is applied, the corner portion Fc of the film F is not likely to be pulled out between the fixed receiving seat 38 and the front end portion 39a of the opening and closing holding piece 39. Since the film winding drum 29 in the state shown in Fig. 15 is rotated after one rotation, as shown in Fig. 16B, since the film F in the film pulling region Fa is wound, the corner Fc of the film F is not at all There is a possibility that the self-retaining receptacle 38 and the front end portion 39a of the opening and closing holding piece 39 are pulled out.

The film F attached to the surface of the sheet material P as described above is wound around the film winding drum 29 while being torn from the surface by the rotation and traverse of the film winding drum 29. When the traverse body 3 (the film winding drum 29) reaches the traverse end position E, the motor 24 of the traverse drive element 8 and the rotation drive motor 34 of the film winding drum 29 are automatically stopped, and the film winding drum is finished. 29 rotation and traverse. Although traversing As shown in Fig. 1, the traverse end position E of the body 3 is a position at which the peeling of the film F at the maximum allowable size of the sheet P to which the peeling target film F is attached is completed, but the sheet P is provided. When the size is small, since the position of the peeling and winding of the end film F is before the traverse end position E, the traverse body 3 can continue to traverse to the traverse end position while continuing to rotate the film winding drum 29. E. In this case, the driving rotation of the film winding drum 29 can be completed at the position where the peeling and winding of the film F is completed.

In the apparatus shown in Fig. 1, since the wound film collecting device 5 adjacent to the traverse body 3 that has reached the traverse end position E is provided, the traverse body 3 that can reach the traverse end position E can be obtained. The film winding drum 29 mechanically and automatically removes and recovers the wound film F. However, the film corner peeling device 4 or the wound film collecting device 5 is not essential to the present invention and can be omitted.

Therefore, it is also possible to tear the corner Fc of the film F from the sheet P without manual use of the film corner peeling device 4, and to position the corner Fc of the peeled film F at the traverse start position S. The film winding roller 29 (film holding member 37) of the traverse body 3 is used, and in the case where the film corner peeling device 4 is used in combination, the structure may be any form. Similarly, the wound film F can be pulled by the film winding roller 29 of the traverse body 3 that has reached the traverse end position E by manual operation without using the wound film recovery device 5, and is accompanied by film winding. The roller 29 is idly pulled in the opposite direction, and finally the step of detaching the film corner portion Fc of the film holding member 37 against the clamping force is applied, and in the case where the film recovery device 5 is used in combination, the structure is also Can be in any form. Depending on the circumstances, the film winding drum 29 with respect to the traverse body 3 can be detached by a simple operation, and the film winding drum 29 from which the film winding ends is taken out from the traverse body 3 reaching the traverse end position E is taken out. And replaced with a new film winding drum 29 before film winding.

Further, in the above embodiment, as shown in Fig. 14, the fixed receiving seat 38 of the film holding member 37 and the opening and closing clamp are held when the traverse body 3 (film winding drum 29) is positioned at the traverse start position S. The positional relationship of the sheet 39 is such that the corner portion Fc of the film F is held between the fixed receiving seat 38 and the opening and closing holding piece 39 by the closing movement of the opening and closing holding piece 39 before the rotation and traverse of the film winding drum 29 is started. When being sandwiched The nip depth of the film corner portion Fc held between the fixed receiving seat 38 and the opening and closing holding piece 39 is extremely shallow. In order to solve this problem, as shown in FIG. 18A, the position of the film holding member 37 when the traverse body 3 (film winding drum 29) is positioned at the traverse start position S, that is, with respect to the film winding drum The position of the axial center of 29 is set to a position slightly forward of the position immediately below the axial center of the film winding drum 29, and in this state, on the circumferential surface of the fixed receiving seat 38 and the peeled film After the corner portions Fc of F are adjacent, the film winding drum 29 is started to be rotated before the closing movement of the opening and closing holding pieces 39 is started. As a result, as shown in Fig. 18B, the corner portion Fc of the peeled film F can be made deeper between the fixed receiving seat 38 and the opening and closing holding piece 39. Since the opening and closing of the holding piece 39 in this state causes the closing portion of the film F to be sandwiched between the fixed receiving seat 38 and the fixed receiving seat 38, the clamping between the fixed receiving seat 38 and the opening and closing holding piece 39 can be increased. The clamping depth of the film corner Fc. Thereafter, similarly to the above-described embodiment, the traverse of the traverse body 3 (film winding drum 29) is started, and the film winding drum 29 which starts the rotation only is traversed, and the desired peeling of the film F is performed. Just around the action.
